The film takes place in the summer of 2019, but in a world still under a dictatorship rule. Daegu Police Counterintelligence detectives In-hyeok and Sang-jun are monitoring Lee Su-gyeong, wife of Choi Myeong-hun, who is wanted for violating security laws. In-hyeok feels compassion for the pregnant Su-gyeong living in hardship. The film is both a road movie about In-hyeok, Su-gyeong, and Sang-jun, and a story about people forced to hide in the mountains from corrupt power.
